IMPROVEMENT IN ROAD-SCRAPERS.

Specification forming part of Letters Patent No. 175,125, dated March 21, 1876 application filed February 5, 1876.

To all whom it may concern Be it known that I, THOMAS MAJOR, of Frankfort, in the county of Clinton and State of Indiana, have invented a new and valuable improvement in Road-Scrapers; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, refegence being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of a plan view of my road-scraper, and Fig. 2 is a longitudinal vertical sectional View of the same. Fig.3 is a side elevation thereof.

This invention has relation to implements for grading and scraping roads and for making ditches; and the nature of my invention consists in a concave shovel or scraping blade, which is pivoted to the rear ends of two draft-irons, to which a tongue is rigidly secured, in combination with locking-joints, which are adjustable and also removable, as will be hereinafter explained.

In the annexed drawings, A designates the scrapingblade, which is concave on that side presented to the earth, and which is connected to the rear downwardly-curved portions of draft-irons B B. a The blade A 18 thus allowed to assume the two positions shown in Figs. 2 and 3, the one for scraping and thc'other for dumping the gathered load.

The draft-irons are rigidly secured to a tongue, 0, and to the ends of a cross-piece, O,

I on the rear end of this tongue, as shown in Fig.1. The scraper-blade A is thus allowed to be oscillated freely when it is not held by a locking device, which I am about to describe.

E E are two handles secured to the blade A, on each side'of a vertically'slotted arm, a, which latter is rigidly secured to the blade at the middle of its length, and has pivoted to it by a removable pin, b, the rear link 0 of the rocking device. Several holes are made through the link 0 for receiving pin 1), and allowing the blade to be adjusted to run at any desired angle. A. handle, 0, is fixed to the link 0, which the driver grasps when he desires to break the joint f. The link 0 is pivoted to the link 0 just beneath astop-lip, 9, formed on the latter, and intended to prevent the joint at f flexing below the point shown in Fig. 2. The front end of the link 0 is pivoted between ears formed on a plate, 0, which is secured to the draft-tongue. When the joint f is depressed as shown in Fig. 1, the shovel A will be locked in scraping position, and the several pivotal connections of the locking device will be sustained from undue strain by means of a stay-chain, 19, attached to hooks 1' 1". When a load has been gathered the attendant dumps it by breaking the joint f.

If desired, thills for asiugle horse may be substituted for the single draft-tongue shown.

What I claim as new, and desire to secure by Letters Patent, is-

lheconcave scraper A, pivoted to the draftirons B, and also to the link 0, by the removable pin b, in combination with the link 0, having perforations for adjustment at its outer end, and provided with the handle 0 and stop-lip g and the pivoted link 0, substantially as described, and for the purpose set'forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

THOMAS MAJOR.
